Perhaps you should try some spelling variations:
luan nhung » luan chung, luan hung, quan nhung
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
chu xanh » chu manh, chua xang, chuc danh
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chieu xanh)) - hanh tang luan nhung ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - hanh tang luan nhung ((cong dan) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - hanh tang luan nhung ((cong dan) or (cong tan)) toan cau*.
